The Snake's Nest

From the publishers blurb:

The Malatir tribe has escaped the goblin hordes that invaded their home after a catastrophic defeat. They have since found refuge in a narrow canyon, occupying some ancient ruins. With them, they have brought six wyvern cubs, a holy creature to the Malatir.

However, the canyon is not empty. On the opposite end of the canyon a group of snake-men have occupied an old dam where they conduct blood rituals and sacrifices to their ancient god, the Anathema.

Now the Malatir are in dire straits, too weak to defend themselves and with the perfect sacrifice for the Anathema in their home. Without help the Malatir are destined to vanish in the throes of a gruesome ritual, their souls lost to an horrid god hunger.
